JOHN L. SCI-IRODE, OF HOPKINSVILLE, KENTUCKY, ASSIGNOR OF ONE-HALF '10FRED- ERICK W. NUNN, OF MARION, KENTUCKY.

GLOBE-VALVE.

To all whom it may concern:

Be it known that I, JOHN L. SoHRoDn, citizen of the United States,residing at Hopkinsville, in the county of Christian and State ofKentucky, have invented certain new and useful Improvements in Globe-Valves, of which the following is a specification'.

This invention relates to improvements in valves of the type commonlyknown as globevalves, and the especial object of the improvements whichform the subject matter of this application is to produce a valve whichcan be interchangeably used either as a straightway valve or as anangle-valve, the same bonnet, gate and valve-seat being used in eitheradaptation of the valve.

Other objects of my improvements are to provide a valve that can becheaply manufactured and in which the gate and its seat can be easilyreground when they become worn from use, and in which the gate will havea tendency to wear the seat so that they will effectively interfit.

In the accompanying drawing I have illustrated a preferred adaptation ofmy invention in the following views Figure 1 is a sectional view on amedianv line through a valve constructed according to my invention; Fig.2 is a fragmentary view in elevation of the valve-gate and its connectedstem.

Referring to the details of the drawing, 5 represents the body of aglobe-valve of common form having three tubular extensions 6, each ofwhich is provided with internal screw-threads 7 of like pitch andcircumference. Extending diagonally of the interior of the body at apoint that will intersect both the vertical and horizontal axes of thevalve, is an integral partition 8 in which is formed an annularvalve-seat 3, said partition and seat being arranged at an angle offorty-five degrees to said axes.

The bonnet 9 is of a well-known form and is provided at its inner endwith a threaded extension 1 which is adapted to be screwed into any ofthe bores 7 and with a threaded extension 10 adapted to receive thecapnut 11.

12 represents the valve stem which is threaded for a portion of itslength as at 13 to engage the internally threaded bonnet. On the innerend of the valve stem is fixed a flanged collar 14 which is externallySpecification of Letters Patent.

threaded to receive the internally threaded portion 15 of the sphericalvalve-gate 16. This ball gate is of suitable diameter to fully cover theseat 8 in the partition 8, and as it turns with the stem 12, has atendency to grind an efiicient face on said seat should there be anyfault in the latter or in the contour of the gate.

As shown in full lines in Fig. 1, the valve is in a straightway form,and as shown by dotted lines, itis in angle-form, the change beingeffected by unscrewing the bonnet from the vertical extension 6, andscrewing it into one of the horizontal extensions.

It will be apparent that the spherical form of the gate lends itself tobeing effectively seated regardless at which angle it is presented tothe valve-seat, and that hence one seat is suflicient for both thestraight-way and the angle forms of valve.

The utility and economy of my improved valve must be apparent to anyoneskilled in the art.

Having thus described my invention what I claim is 2- 1. A valvecomposed of a body having a plurality of bonnet-receiving extensions,and having a valve-seat arranged to intersect the axes of saidextensions, a bonnet adapt ed to be interchangeably connected with saidextensions, and a valve member having a stem arranged in said bonnet andcompris ing a gate connected with said stem and adapted to cover saidseat.

2. A valve composed of a body having a plurality of bonnet-receivingextensions arranged at angles to each other and having a valve seatarranged to intersect the axes of said extensions, a bonnet adapted tofit said extensions, a valve-member comprising a stem adj ustablymounted in said bonnet and a gate detachably connected with said stem.

3. A valve composed of a body having a plurality of bonnet receivingextensions arranged at angles to each other and having a valve seatarranged to intersect the axes of said extensions, a bonnet adapted tofit said extensions, and a valve arranged to rest on said seat.

In testimony whereof I aflix my signature in the presence of twowitnesses.
